TELEGRAPH INDICATOR.

Application filed December 15, 1921. Serial No 522L641. Renewed February23. 192's.

This invention relates to new and useful improvements in telegraphiclnstruments and more particularly to a device used for indicating thecurrent impulses which are passing through the instrument by means ofthe usual well known code form which isfamiliar to telegraphic operatorsand which can be read the same as though received dlrect from the typeof telegraphic relay instrument illustrating my attachment appliedthereto;

Fig. 2 is a sectional view taken on the line 22 of Fig. 1

Fig. 3 is a sectional view taken on the line 33 of Fig. 1, and 1 Fig. 4is a detail perspective view of the indicator itself. 7

Referring now more particularly to the drawings, the numeral 1 indicatesa base upon which the telegraphic mstrument 1s supported. said relayinstrument being 111 the present instance of the well known type oftelegraphic relay instruments including a magnet 2 having an armature 3of a relay of the well known type disposed at one end thereof.

7 My improved indicator comprisesin detail, a tubular standard 4 mountedupon the base 1 in front of the instrument. and preferably arranged inclose proximity to one of the magnets 2 as is clearly, illustrated inFig. 2.

Mounted for vertical sliding movement with- I in this standard 4 is thevertical portion 5 of an angular bar, the horizontal portion 6 of whichbridges the space between the standard 4 and the magnet 2 at a pointabove the standard and has a hook member 7 suspended from the horizontalportion 6 at a .point adjacent the outer end'thereof. Suspended from thehook 7 is a leaf indicator 8, which will be drawn toward the magnet 2 asthe impulses of current pass through the magnet.

The member 5 is adjustable within the standard 4 and secured in variousvertically adjusted positions by means of a set screw 10 I which extendsthrough thewall of the standard 4 and binds against the member 5'toretain the same in an adjusted position.

Mounted upon the standard 4 at the upper end thereof is a sleeve 9having anarm 12 projecting outwardly at right angles thereto andprovided at its outer end with a ring 11 1 like a sounding fork. Fromthisit will be apparent that impulses passing through the magnet 2 inthe code form familiar to telegraph operators, will be indicated throughthe leaf 8 being drawntoward the core and even though these vibrationsare not strong enough to move theleaf into contact with the ring 11.they will be visible to the operator and he can read the same as thoughthey were received direct from the sounder in the regular way.

It will be understood that the impulse currents which operate the leafmember 8 arecomparatively feeble requiring close attention of theoperator at the receiving instrument to enable the operator to read thevibrations passing through his instrument to the receiving ringattachment. This device provides a never failing circuit indicator,always point ing out to the operators the wire condition v and perfectadjustment of his instrument as the operator can readily see at a glancethe condition of his instrument and the circuit and whether or not theyare working in conjunction with each. other and are properlyfunctioning. t

Usually telegraph relay instruments are so adjusted that even though thebattery be alive the instruments will be unaffected perceptibly, and theoperator unable to tell whether the battery is alive or not. It will beobvious that by reason of mounting the leaf member 8 and its lightweight that this attachment will be affected by the current when theinstrumentitself itself will'be unaffected a'nd'that the vibrations ofthis leaf will be visible to the operate)? and indicate to I him thecondition of the wire. It will also be apparent that by supporting thering member 11 in a position to surround the lower end of the leafmember 8, the leaf when vibrated through the impulses passing throughthe magnet, will tend to be forced into contact with the ring 11 andthus produce an audible signal in addition to the visible signal. Thedevice also provides means whereby the regular code form-may be conveyedto the operator when the instrument itself is unai'fected,

because if there be sutlicient litfetin the but tery to convey theimpulses to the leaf memher '8, theleaf member Wlll strike against thering 11, thus picking up the current impulses Y which are passingthrough the magnet in the code form so that they may be readby theoperator the same as though received through the telegraph sounder inthe regular way.
